An experimental attempt to make yet another VPN-based "firewall" for Android without root access. The main motivation is to have a simple approach and a clean UI.

Android's VpnService can route selected apps through a VPN tunnel, so the kernel drops the
blocked apps' packets; everything else keeps going through.
NetGuard is the mature project here, and if you want per-network rules, traffic logs, or hosts-based ad blocking, use it — genuinely. Netblock exists to embrace simplicity and to do one thing and do it well.
Needs Android 8.0 or newer. Grab the APK matching your device architecture from the
releases page — arm64-v8a for most modern
devices, or -universal.apk as a fallback if you're not sure.
On first launch the app walks you through the needed permissions.
I'm not going to pretend I've made this app entirely by hand, but I used AI to scaffold the boring parts, brainstorm, and iterate.
